SHUTTLE Application ledFebruary 27, `ISEBS. Serial No.. 257,137.

This invention relates to shuttles and `particularly to shuttles used in `weaving silk and other fine filaments, in which the filling or wett tension means Iis required not simpl to :impose a drag on the filling but to Italie up any slack that may otherwise result as an incident ofV the action of the shuttle and the nature ot' the filling, so that :for this purpose the tension means comprises members coacting to maintain a bend or bends in the filling and one of which at least .is yieldable to the filling. `The principal object of the invention is to provide a reliable and efiicient tension device of this class Y' which is adapted to receive the filling by movement of the latter transversely of it.- selt between the members ot the device and which will periorm this operation unfallingly when the loom of the class in which re ilenishing ot the filling package when exhausted is accomplished automatically.

In the drawing,

Fig. l is a plan of a shuttle embodying the improved tension means;

Fig. 2 is a fragmentary side elevation;

Fig. 3 a section on line 3 3, Fig. l; v Fig. l a longitudinal substantially central fragmentary section;

Fig. 5 a fragmentary plan with the overhanging nose omitted;

Fig. (i an underneath plan of said nose; and

Fig. 7 a section on line 7?, Fig. 1.

The shuttle body l has the 'usualn opening 2 for the filling package 3 whose quill 4 is supported in some well known way so that when the package is exhausted the empty quill may be automatically expelled downward from the cavity and a fresh orfull package substituted. This operation occurs as usual when the shuttle is in the shuttle box which in the present example would he at ,its right in Fig. 1.

Opening 2 has an extension 5 between it f and the right hand end of the body which forms cavity in the. latter open at the top and this cavity is Yformed with a lateral notch G which at its lower end is elongated, as at 7,- and forms the filling outlet of the shuttle. A nose 8 is provided on the shuttle body, projecting to the right and being secured at the near side of cavity 5 in Fig. 1 but extending clear of the op osite side, all in such manner as to permit t e filling, on a threading operation and when trailing straight from the shuttle as it moves to the 13 in place.

ing guides.

left, to enter the cavityat the far side of the nose in Fig. l, and then, on a bight being formed" in the fillingwhen the shuttle next passes tothe right, to enter the Outlet 7 via the slit left at 9. i n

Where the cavity 5 joins the opening 2 there is preferably a Well-known type of filling grip device comprising a` housing y10 fitted in the shuttle bod `and a pair of filling clips 11 therein hel by springs 12. 'Wheat-he filling intrailing straight from the shuttle as it passes to the left enters cavity 5 it enters between the clips and becomes gripped thereby.

Between this device and `the apex ofthe nose 8 is arranged the improved tension device comprising two members generally designatec 1 3 and 14 in Fig. 1 and adapted to. maintain the receivedfillin'g normally lexed and one (14) being yieldable to per mit it to straighten when tautened; in the example eaclrof these is shown formed of wire. `The fixed member is formed with an upright portionda `which adjoins the side o the cavity 5 opposite that Vhaving outlet 7 and which islspaced from the nose Stand against eachother n reaches downward, a portion 13b inclined i downwardly from the lower end of portion 13 and across the cavity 5, underthe nose, a portion 13C extending downwardly "from the lower end of portion 13b and a. returned end portion 13, each of these portions is preferably duplicated byfirst rebending` the wire on itself andthen bending both extremities thereot to form them, and the rebend-` ing may be donein such a wa as to leave a tang or stub 13` which may iedriven into a hole 15 in the shuttle body to hold member A filling rest is thus formed at 13" which slopes downwardly and off which at itsY lower end the llinvmay fall to be thereupon held normally fibxed by the p0rtion 13 of this member andportions .0f the other member 14; said portions 13 `are formed with concave seats forthe filling, as shown best in Fig. 3, so as to serve as fill- The movable member 14 is formed with a pivoting eye 14, a short arm 14' projecting therefrom and a long arm 14 providedwith, in the present case, three substantially parallel portions 14d each extending lengthwise of the axis of eye lt` and resulting from bending the wire`in two loops lying in the same` plane; said member isa lever whose eye 14 has a bearing on a pin or screw 16 in the bottom of the cavity 5 so that Iits portions 1ll stand uprighh they being so situated as to alternate with the extremities of the (binary) member 13. These portions 14d are the filling guides of member lll, and they extend above the fillrest 13" and have their upper ends bentoff toward the portions 18L of member 13,

`or away from the side of cavity 5 having outlet 7. Member A: is normally held, by an elastic 17 connecting itwith an adjustingscrew 18, with its extremity 11ie bearing against the side of cavity 5 opposite that having outlet 7. At the far side of the nose 8 in Fig. 1 a filling passage 19 is left 'which may be taken as extending between the portions 13 of member 13 and said nose (see Fig. The level of outlet 7 is Well below this passage.

lllhen the shuttle is fully thr led the filling extends from the quill, between the clips 11, between the guides of the ineinbers 13 and 14, under the nose 8 in a bight, and then out at outlet 7 it is retained between the guides due to those 13C being concave. Consequently the members 13 and 14 act in a well known way to maintain tension on the filling.

The threading is thus effected: lVhen the filling, as in trailing the shuttle on the substitution of a fresh for an exhausted package, drawn straight to the right it enters passage l9land between clips 11 and lies upon the rests 131 Vhen, thereupon, it is formed in a bi ght under nose 8 and reaches outlet 7 through slit- 9, as whenthe shuttle now moves back to the right in Fig. 1, it encounters the upper ends of portions left of member 14- and shifts this member to the outlet side of the cavity and then falls to position between guides 13 and lll, thus completing the threading. The filling grip device formed bythe clips 11 is not indispensable, but it is desirable; without some such device'to hold down the filling once it fnlly enters the passage 19 itislilely to be whipped out of the passage as it is paid from the package, which at that time has its maximum diameter. Although the component parts of each member are preferably formed of the saine piece of material, as wire, it will be .understood that as long as kthere are co-acting means, as 13C-1-l-d, to

maintain abend or bends in the filling and down between which the filling is enterable, one of said means being movable toward and from and elastically urged from one side of said body, and also a rest, as 13b, for the filling having a guiding surface for the thread inclined downward toward said side and merging into the guiding surface of the other of said means and having the Inovable one. of said means projecting in its normal position across such surface, the invention will be accomplished.

Having thus fully described our invention, what we claim is:

1. In combination, a shuttle body having means to receive and hold a filling package and also having an upwardly open cavity between said means and one end of the shuttle, co--acting means in the cavity to main tain a bend in the filling and down between which the filling is enterable, one such means being movable toward and from and elasti- V:ally urged from one side of the body, and a rest for the filling arranged in said cavity and having a guiding surface for the filling inclined downwardly toward said side of the body and merging into the guiding surface of the other of said means, said movable one of the co-acting means projecting in is normal position across the rest `in sharp angular relation thereto.

2. ln combination, a shuttle body having means to receive and hold a filling package and also having an upwardly open cavity lietween said means and one end of the shutile, and a fi. g outlet leading from the cavi y to the exterior of the body at one'side of the latter. co-acting means in the cavity lo ni i tain a bend in the filling and down betweenwnich the filling is enterable, one such inea 1: being movable toward and from and elastic-ally urged from said side of the body, and a rest for the filling arranged in said cavity and having a guiding surface tor the filiing inclined downwardly toward .said side of the body and merging into the guiding surface of the other of said means, said movable one of the co-acting means projeling` in its normal position across the rest in sharp angular relation thereto.
